# contentRuleListStoreRemoveFailed

An error that indicates a failure to remove a content rule list from the rule list data store object.

```
static var contentRuleListStoreRemoveFailed: WKError.Code { get }
```

## Discussion

A [`WKContentRuleListStore`](/documentation/WebKit/WKContentRuleListStore) object might return this error if it’s unable to delete the persistent copy of the rule list from the user’s system.
